c# - 如何使用 CRM Dynamics 2013/2015 中的插件更新 CRM 中的实体和相关实体

Question

我是 CRM 的新手，我正在努力使用插件更新实体，我已在创建消息时的 PhoneCall 实体预操作上注册了一个插件，然后，当我查询相关实体并将数据从相关实体写入我的 PhoneCall 实体时，尽管我似乎收到一条错误，表明 GUID xxxxx 的记录不存在。

下面是我的代码；

  public void Execute(IServiceProvider serviceProvider)
    {
        ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
        IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

        if (context == null)
        {
            throw new ArgumentNullException("localContext");
        }

        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

        IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

        if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
        {
            Entity phoneCallEntity = (Entity)context.InputParameters["Target"];

            if (phoneCallEntity.LogicalName != "phonecall")
                return;


            if (context.MessageName == "Create")
            {
                try
                {
                    QueryExpression qe = new QueryExpression("new_zoiperhistorydata");
                    qe.ColumnSet = new ColumnSet("new_regardingobjectid", "new_callduration");

                    var ZoiperData = service.RetrieveMultiple(qe);

                    if (ZoiperData != null && ZoiperData.Entities.Count > 0)
                    {

                        foreach (Entity entity in ZoiperData.Entities)
                        {
                            if (entity.Attributes.Contains("new_callduration"))
                                phoneCallEntity.Attributes["new_callduration"] = entity.Attributes["new_callduration"].ToString();
                        }
                    }

                    service.Update(phoneCallEntity);
                }
                catch (System.Exception ex)
                {
                    Console.WriteLine("The application terminated with an error.");
                    Console.WriteLine(ex.Message);

                    // Display the details of the inner exception.
                    if (ex.InnerException != null)
                    {
                        Console.WriteLine(ex.InnerException.Message);

                        FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> fe = ex.InnerException
                            as FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>;
                        if (fe != null)
                        {
                            Console.WriteLine("Timestamp: {0}", fe.Detail.Timestamp);
                            Console.WriteLine("Code: {0}", fe.Detail.ErrorCode);
                            Console.WriteLine("Message: {0}", fe.Detail.Message);
                            Console.WriteLine("Trace: {0}", fe.Detail.TraceText);
                            Console.WriteLine("Inner Fault: {0}",
                                null == fe.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
                        }
                    }
                }


            }

代码在 service.Update(phoneCallEntity) 上失败；

问题在于您在创建事件的预操作阶段运行插件。实际上，电话调用未在此阶段创建(并且没有 ID)，并且您会收到报告的错误消息。 实际上，您不必使用 service.Update 方法自己更新电话。由于操作贯穿始终，您只需在 Target 上更新您喜欢的字段，然后让 CRM 完成其余的工作:)
